" It will; thus seen the :"housis properly ffd-ispo'sed through the openingB'ef theusualfurnacsti'ucture, 'gas'ma the interior of I passagethrough the opening 1n the adaptedffor disopen at both ends, a removable cover plate at be fed under pressure through the supply pipes 8 and into the manifold pipe 3. The pressure of the gas will pass downwardly through the manifold, until it engages and compresses against the plates 9 at the bottom thereof; At this stage, the gasbaoks upwardly, passing into the branchfpipes l4 and 15 respectively. As a result of this gas movement, the same discharges through the jet pipes-16 and 23 respectively. The gas in passing from the ends of the jets draws air from the housing, and mixes durns t jetblock. ,The end jet of both. the I upper and. lower branch pipes of the manifold, are'regnlatable bythe control valves 1.7 a'ndQ l respectively.

these valves are in closed position, only the intermediate "jets are being employed. H0wever,'when it isdesired to increasethe power, these valves maybe opened or' regu-' lated as desired.

' The sliding'closuresattheside df'the hous ings, are adapted to be opened to increase the air supply. to the flame, I the sides allowing access to the interior of the' caslng, whereby the lowenvalve may be operated.

Themanner in I which thejet pipes are "arranged laterally projecting from the branch p pes, and not 4 directly from the verticalextent of the mani fold, allows the gas to-bank-ptherein, and distribute equally into'the branch pipe.-
